IV. 3. Operating principle
The compressor sends filtered ambient air to a group of valves, which allows
compressed air to pass to the column in production. The columns contain a
molecular sieve, whose function is to adsorb the nitrogen and thus
allow oxygen to pass. The oxygen enriched air is then directed to a pressure
reducing valve through the flow control valve to the oxygen outlet fitting.
During this time, the column which is being “regenerated” is connected to the
ambient air and a current of oxygen enriched air is passed through it (from the
column “in production”). In this way, when one column is in production, the other
is in a nitrogen desorption or “regeneration” phase. The oxygen enriched air
finally passes through a product filter situated prior to the oxygen therapy outlet.
